A useful knife for opening uncut signatures is the sculptor's fettling knife (#97 or #96) which can be found in most art supply shops. A dulled blade slides precisely into the apex of the folds before it starts to cut. The blade is thinner than most paper knives sold for slitting envelopes and the tip is rounded so you won't puncture the paper by accident.
